Liguria-FUEL BURNER.

` Be it known that l, EMIL citizen of the United States,vre'siding atVictoria, county of Victoria, State of Texas,

have inventedcertain new and useful Improvements in Liquid-Fuel Burners,of whichthe' following is .a specification.

This invention relates to improvements in liquid fuel burners. -f

lOne of the objects is to produce afburner adapted to-generate gas fromliquids rich inv hydro-carbons andconsume the same 1n an j economicalmanner. s

And finallyY to produce a heating system, adapted for use in private orpublic buildings, that requires practically no labor or supervision, thesame operating continuously so long as a fuel supply is maintained.

These and other objects are attained by vthe novel combination andconstruction of parts andprinciples hereinafter, described, and shown inthe accompanying drawings, forming a material part of this disclosure,and in which Figure 1 is a longitudinal view ofl a heater made inaccordance with the invention, partly in elevation and partly insection.

Fig. 2 is a transverse sectional view of the same taken on the line 2-2of Fig. 1, the support for the nipple being omitted.

Fig. 3 is an enlarged vertical sectional view taken through one of theburner heads.

Fig. 4 isa top plan view of the same.

Referring now more particularly to Figs. 1 and 2 of the drawings, theburner shown is comprised of a pair of rigid end Yplates 10 and 12joined by a thin deflecting or cover plate 14.

Also connecting between the end plates, near the bottom isconcave-convex plate 16, having thickened edges 17, forming a jtrough-like receptacle for purposes further indicated.

Liquid fuel is supplied to the burner through the feed pipe 20, having acontrol valve 21, engaged with the tubular element 22 of the heaterwhich passes through the end plate l2, below the cover 14, and isengaged at its opposite endv with an elbow 23 having a plugged opening24.

`Engaged in the vertical opening of the elbow is a nipple 26 held by aclip 27 tothe end lplate 10, and engaging the nipple 1s another elbow'28similar to the elbow 23, both of which are partially contained in arecess 29 formed in the plate l0.v

R. BITTNER, a 1

Patented June i VEngaged `in theother `opening of the i" elbowY V28 isanother tubular element 32, forming a U bentwith the tube 2v2,- andextending out throughthe end vplate 12, the end of the tube beingcovered by the flange Extending diagonally -downward from bases34'formed withthe tubeA 32into recesses 35, are two pipes 36,Vscrew-threaded intoV valve casings 38 set in the lower portionsofthe'recesses 35,fin ,whichtheyare held by the cover .plate39. Thesevalve casings 38 are hollow and have outwardly extending hubs 40receptive lof the screwthreaded stems 41, having on their extending endshandV wheels 42, while-the inner i ends of the stems areformed, intoVconical valves'43, extending through the oppositely` disposed hubs 44of Ythe valve casings S8,- and are adapted to the valve seats 46 formedin blocks 45at the ends ofthe hubs 44.

. Engaged exteriorly of the hubs 44 and adapted to retain the blocks 45inposition, are other horizontal tubular'elements or cylinders 48 havingplugs49 in their'opposite end which rest in recesses formedl in the endplate l0.

Set radially in the cylinders 48 are two rows of spaced,V burner heads52, the inner row of each cylinder being directed toward the tube 32 andinterposed therebetween is a iiame breaker comprising a bar 55 onwhichvrare spaced a plurality of thin plates 56,1the" upper wider endsbeingclosely adjacent to the tube 32, to which the bar 55is parallel,

it being held direct in the end plate 12 at one Y, end and in a bracket57 at the other, the

bracket being attached to the plate 10.

The burner heads or tips 52Vare each formed with a screw-threaded stem60 conv taining a conical opening 61 in communication at its base withthe interior of the cylinder 48, while its upper end enters a mixing lnoperation liquid fuel being supplied through'pipe 20 from any suitablesource the valve 21 is turned on until it flows out of the tips 52 intothe trough or pan 16 and there ignited. The heat thus generatedV sooncauses the liquid inthe burner tubes-48 to gasify and eventually asimilar effect takes l place in the 'tube 32 so thatbyv adjusting thevalve hand wheels 42 gas may be delivered to theburner tips in desiredquan- -Y tity, the pan 16 being used only while start- Vin vtheburnerinto operation.

Iaving thus described my invention what I claim as new and desire tosecure by Let# of ters Patent isz-- K Y therebetween, means forcontrolling the inlet o-fuel to the upper oli-said tubes, a pair of l. Afuel oil burner comprisinga pair'of'- horizontal tubes, disposed oneover the other, al -U-shaped--bend connecting at one end divergent"pipes engaged with the vlower of said tubes, 'valve caslngs engaged withthe lower end of ysaid pipes, control valves insaid casings,longitudinally extending cylinders l'engagedin said heads, a pluralityof burnl ers in said cylinders, a bar extending Vbelow vsaid tubes andaplurality of'plates secured to "said bar over Vsaid burners whereby heatmay beconverged thereto.
